愤怒身段表情的视觉搜索优势

The Visual Search Advantage of Angry Body Posture

愤怒面孔作为威胁性情绪信息存在视觉搜索优势,被称为“愤怒优势效应”。身段表情是非言语情绪信息的重要来源,与加工面部表情存在类似的行为和神经机制。本研究运用视觉搜索范式,考察真实的身段表情是否能像真实的情绪面孔一样存在愤怒优势效应。结果发现,无论在中性还是情绪性,愤怒身段表情的搜索速度均快于悲伤身段表情;在没有目标的序列中,愤怒身段表情的搜索速度依然比中性和悲伤的搜索速度更快。真实愤怒身段表情存在视觉搜索优势,证明真实身段表情的确是有效的情绪信息来源。

The visual search advantage of angry faces as threatening emotional information is known as “anger superiority effect”. Body posture is an important source of nonverbal emotional information and has a similar behavior and neural mechanisms with facial expressions. The present study uses the visual search paradigm to investigate that whether real body postures have anger superiority effect as real emotional faces. Results confirmed that angry postures are found more quickly than sad postures in crowds of both neutral and emotional distractors;in the target-absent array, the search speed of anger postures is faster than that of neutral and sad postures. There is visual search advantage in the real anger postures, which demonstrates that real body postures are an effective source of emotional information.
